The Shattering, by Karen Healy (Little, Brown, 2011)

Keri, Janna and Sione have one thing in common: they’ve each lost an older brother under tragic circumstances. Convinced that it’s more than coincidence, they dig deep, discovering a rash of similar deaths over the years, all linked to their peaceful New Zealand town. Now they have to deal with a supernatural threat which stands ready to take another life in the near future. Can they unmask their enemy before anyone else gets hurt? With a multicultural cast, an intriguing setting, and a genuine sense of mystery and foreboding, this is an unforgettable read. The characters are rich and complex, the magic is subtle, and the story satisfying.
